Answer:

Oxidation reaction

Explanation:

When flame comes in contact with gasoline in the presence of oxygen, combustion takes place. Oxidation reaction involves reacting oxygen with a compound. To stop fire, we can stop the oxidation process by adding carbon (iv) oxide since it does not support combustion. Hence the reason why CO2 is used to stop flames.

C + 2H2 -> CH4

ankoles [38]

Answer:

C) 4

Explanation:

The reaction :

C (s) + 2H₂ (g) ⇒ CH₄ (g)

12g 4g 16g

Hence, based on this we can say that : 2 moles of hydrogen gas are needed to produce 16g of methane.

For 32g of methane

Number of moles of H₂ = 32/16 × 2
Number of moles of H₂ = 4

Determain the number of moles in 2.24l of ch4 at stp

valkas [14]

Answer:

0.1 mole of CH₄

Explanation:

From the question given above, the following data were obtained:

Volume of CH₄ = 2.24 L

Number of mole of CH₄ =?

The number of mole of CH₄ can be obtained as follow:

Recall:

1 mole of a gas occupy 22.4 L at stp. This implies that 1 mole of CH₄ occupies 22.4 L at stp.

22.4 L = 1 mole of CH₄

Therefore,

2.24 L = 2.24 × 1 mole of CH₄ / 22.4

2.24 L = 0.1 mole of CH₄.
